[OE-core] [PATCH V2] tclibc-musl.inc: fix bfd "cannot make copy relocation for protected symbol" issues

[Ming Liu]

Hi, Burton:

I also agree with you, your suggestion is better.

Hi, Khem:

But is this a bug of binutils? Or musl libc? Since I had only observed this
error with musl libc only, it did not occur with glibc.
